My boyfriend is called Sijtze, another spelling of the name. It is very unique but anyone that isn't dutch will have troubles pronouncing or even remembering it.

In the Frisian-speaking world, Siet is used as a masculine name in West Frisia (located in The Netherlands) only. It is quite common, especially when compared to the original from which it was derived (Siet, which is quite uncommon).
